We're sorry, but the Palm Pixi's rendition of Need for Speed no longer impresses us -- we've just seen John Carmack show off Rage for iPhone. While of course it looks nothing like the PC graphical monstrosity that swept the E3 Games Critics Awards, it's safe to say the 60 frame-per-second tech demo at QuakeCon 2010 shoves the cell phone gaming envelope through a Juggernaut-class brick wall. Where Carmack originally called the iPhone "more powerful than a Nintendo DS and PSP combined," the id Software co-founder is now aiming squarely at the likes of PS2 and Xbox with iPhone 4 hardware. Not impressive enough? He says it still "runs great on an original 2G iPhone" as well. VG247, who liveblogged the event, reports the title will be available in the App Store later this year for a relatively inexpensive price, with a second game available in time for the PC game's 2011 launch. Sadly, there's as of yet no plans for Android owners to get the same megatexturing goodness. Don't miss the video after the break, because this screenshot doesn't do it justice.
